Perhaps you should try some spelling variations:
multiling » multilingue
multilingues » multilingueues, multilingue, multilinguismo
{uml}siso." » {uml}sieso.", {uml}sido.", {uml}sino."
{uml}sismo." » {uml}sismos.", {uml}mismo.", {uml}simo.", {uml}smismo.", {uml}sistmo.", {uml}siso."
{uml}miso." » {uml}mismo.", {uml}misio.", {uml}omiso."
{uml}ismo." » {uml}mismo.", {uml}istmo.", {uml}iso."

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "(multiling OR multilingues)((({uml}siso." OR {uml}sismo.") OR {uml}miso.") or {uml}ismo.")~.
• Removing quotes may allow a broader search: (multiling or multilingues)((({uml}siso. OR {uml}sismo. ) or {uml}miso. ) or {uml}ismo. )~.
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingues)((({uml}siso." OR {uml}sismo.") or {uml}miso.") or {uml}ismo.")*.
